Forums settings

Hi. I use forums, and I have installed advanced forum ( 1.x for Drupal 6.x), on my drupal site.
I would like the forum show topics and comments like drupal forum, that is:
- In topics list, the newest topics or topics with new comments are shown in the beginning of the list.
- In a particular topic, comments are ordered inverse, that is, the oldest replies are shown in the beginning and the newest at the end.

If I configure forum order options to "Date - first the oldest", then topic list are bad ordered, but comments in a topic are good ordered. If I configure "Date - first the newest", then topic list are goor ordered (showing the newest topic at beginning), but comments are ordered bad (inverse).

How could I have an ordered forum like "drupal forum".

Another question. How could I block the "reply this comment" link. I would like all comments was replys to topic, and not to some particular comment.

Thanks.
